I troubleshoot this problem daily and most of the time it works for me and many others I have helped. Have you all tried to go to your settings> update and security> "check for updates"
If you have "pending restart" then restart then go back to check if your windows update is now up to date, if you have an error message telling you to rety then you need to increase the size of your partition (google it). Mac users you go to your apple icon >system preferences ( or something like that) > general and check your updates. Very important step to skip.....
When your device is needing these cumulative updates and/or security updates nothing you are trying is going to work. It cant
then open a google browser or whichever you use and clear the cached sites and cookies then a safety check. Note: the security is there to keep your information safe I do agree there should be clearer instructions. I like to call it road blocks you need to clear before your information is sent online.
Now open your turbotax program from the top of the screen... see. file edit view online help, click online>check for updates then start a new return and update again go back to your return open it up and try and import as directed
And finally you can try to choose few accounts at a time you also may need to be on an ethernet cable or reset your modem and router.
other options : sign in to your broker account change your password > log back in to broker acct check your forms are there>exit and relaunch turbotax> again you should update the program from the online on the top of your screen. check that you have do not allow 3rd party accessI. Good luck I hope this helps.
